HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 583,969, dated J une 8, 189'?.

Application filed November 14, 1896. Serial No. 612,150. (No model.)

This invention relates to that class of hose# nozzles wherein a nozzle-body is provided with opening and closing deflectors or jaws for discharging the liquid or water in a fiattened sheet.

The chief object of my invention is to improve the prior constructions of such nozzles and to provide new and improved means for applying pressure upon opposite sides of a cylindrical stream of liquid or water issuing from the cylindrical bore of a nozzle-body in such manner that the stream is fiattened and delivered in a wide sheet or spray, the dimension or size of which is controllable by the op: erator through the medium of a simple and easily-operated device.

To accomplish these objects, my invention consists in the combination of a nozzle-body having an external collar, a rotary sleeve having a pair of opposite laterally-proj ecting camribs and. mounted on the nozzle-body at one side of the collar, a nut or plate secured to the nozzle-body and confining the sleeve against longitudinal movement while permitting it to rotate, and opening and closing deflector-jaws pivoted to said plate and having tailpieces respectively acted upon by the cam-ribs of the rotary sleeve.

The invention also consists in certain other features of construction and combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure I is a side elevation of a hose-nozzle constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail top plan view of one of the deiiector-jaws. Fig. 4 is a plan view of the nut or vplate to which the deflector-jaws are pivoted. Fig. 5 is an end elevation of the rotary sleeve having the laterally-projecting cam-ribs, and Fig. (i is a plan view of the spring for pressing the deflector-jaws apart or to their open position.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein- The numeral l indicates a nozzle-body, which, as here shown, is of tapering 'form and is provided at one end with a screw-socket 2 for engaging the hose or hose-pipe to which the nozzle is to be applied. The nozzle-body is constructed with a substantially cylindrical bore and is provided at its outer end with an external screw-threaded portion 3, at the rear of which is formed a cylindrical hearing et and a lateral annular collar 5, which is prei? erabl y integral with the nozzle-body- The cylindrical bearing 4: serves to receive and more or less accurately fit the interior of one end of a sleeve G, which abuts the collar and is formed integral or otherwise provided with two external cam-shaped or inclined ribs 7 and 8. These ribs project late-rally from the sleeve and gradually increase in height from one end to the other, as will be readily understood by reference to Fig. 5. The sleeve 6 is also formed integral or otherwise provided with a cylindrical extension 9, which en circles the nozzle-body and is so constructed and arranged that thehand of the operator can grasp the same and convenientlyv and quickly rotate the sleeve upon the cylindrical bearing fi. I prefer to corrugate, roughen, or serrate the external surface of the cylindrical extension 9 to facilitate the rotation of the sleeve, but I do not wish to be understood as confining myself to the corrugated, roughened, or serrated surface.

The sleeve G is retained in position upon the cylindrical hearing el and is prevented from longitudinal movement through the medium of a nut or plate lO, (best seen in Fig. 4,) which is screwed upon the threaded portion 3 at the outer end of the nozzle-body, whereby the sleeve 6 is more or less loosely confined between the collar 5 and the nut or plate. By this means the sleeve is free to rotate or turn upon the nozzle-body, but is held in proper operative position thereupon and is prevented from undue movement longitudinally of the nozzle-body.

The nut or plate I0 is approximately square, and two of its sides are beveled, curved, or inclined, as at 12, while its other two sides are each provided with two pivot-pins 13, prefen IOO ably formed of metalscrews fitting screwthreaded sockets in the nut or plate. These pivot-pins constitute pivotal bearings for the two deflector-jaws 14, which are so mounted upon the pivot-pins as to provide rearwardlyprojecting tailpieces 15, which bear against the cam-shaped ribs 7 and 8 of the sleeve G in such manner that by rotating the sleeve in one direction the tailpieces will be gradually and uniformly moved outwardly for the purpose of closing the two deflector-jaws toward each other. The deilector-jaws are constructed, respectively,with side flanges so relatively arranged that the flanges on one jaw may move between the flanges on the other jaw to permit of the outer ends of the jaws being brought into comparatively close relation to each other, in order that they will discharge the liquid or water in a flat sheet or stream.

The interiors of the deflector-jaws are provided with shoulders 16, (best seen in Fig. 2,) which are located in proximity to the nut or plate 10 in such manner that a circularlyshaped wire spring` 17 can be seated between these shoulders and the nig-roi' plate, so that the spring is thereby secured and retained in position without the employment of extraneous fastening devices or means. The spring is practicably a split elastic ring having its free extremities 18, Fig. 6, adapted to bear against the internal surfaces of the deiiectorjaws at points slightly in advance of the pvot-pins 13, so that the spring constantly tends to press the 4outer ends of the deiiectorjaws away from each other.

The side flanges of the detlcctor-jaws 1i are cut away, as at 19, to provide lateral air-inlet orices by which air may enter into the jaws when they are closed together and the sheet of water is being discharged in the form of a flat sheet or stream.

The stream of liquid or water will, in the practicable use of the nozzle, issue from the front end of the nozzle-body in a substantially cylindrical form. The deflector-jaws, if closed or nearly closed, exert pressure upon two opposite sides of the cylindrical stream after it has left the nozzle-body and causes this stream to flatten out and spray in a wide iiattened sheet which may be varied from ten to forty feet wide, as desired by the operator, according to the dimensions parts.

The efficiency of my improved construetion is due in a large measure to the fact that the opening left after the deflector-jaws are closed is considerably greater in area-say twenty-live per cent. greater-than the opening through which the water emerges from the nozzle-body, and, furthermore, the openings at the sides of the deflector-jaws induce a current of air. By the means described the flattened column of water will be freely discharged and delivered over a very large area.

Another desirable and important feature of my invention resides in the fact that a comparatively small movement of the sleeve G eifects the opening or closing of the two de- Hector-jaws. A quarter-turn of the collar is sufficient to close the detlector-jaws, and this is very advantageous over prior constructions where a conical nut requires to be moved a considerable distance in screw-threaded engagement with the eXternal surface of the nozzle-body for the purpose of closing or opening the pivoted deliector-jaws.

As before stated, the movement of the sleeve in one direction effects the closing of the two deiiector-jaws. The opening movements of the two jaws are permitted by turn-` ing the sleeve in the opposite direction, so that the spring is permitted to throw the two jaws apart. The pressure of the liquid or water against the internal surfaces of the jaws of course tends to open the jaws, but the spr-ing is desirable in that it secures a uniform and steady motion of the jaws as they open.

Having thus described my invention, what I claim is 1. The combination of a nozzle-body having a collar, a rotary sleeve having a pair of opposite, laterallyprojecting cam-ribs and mounted on the nozzle-body in juxtaposition to said collar, a plate secured to the nozzlebody and holding the sleeve against lateral motioniwhile permitting it to rotate, and

opening and closing detlector-jaws pivoted to said plate and having tailpieces respectively acted upon by the laterally-projecting camribs of the sleeve, substantially as described.

2. The combination of a nozzle-body, a rotary sleeve having a pair of opposite, laterally-projecting cam-ribs, means for holding the sleeve against lateral motion while permitting it to rotate, and pivoted delectorjaws having tailpieces respectively acted upon by the laterally-projecting cam-ribs of the sleeve, substantially as described.

3. The combination of a nozzle-body having a screw-threaded end and a collar near the screw-threaded end, a rotary sleeve having a pair of opposite, laterally-projecting cam-ribs and mounted on the nozzle-body between its collar and the screw-threaded part, a nut or plate engaging said screw-threaded part and confining said sleeve in position, and opening and closing deflector-jaws pivoted to the nut or plate and having tailpieces respectively acted upon by the laterally-projecting cam-ribs of the sleeve, substantially as described.

4t. The combination of a nozzle-body, a rotary sleeve having a pair of opposite, laterally-projecting cam-ribs and mounted on the nozzle-body, a nut or plate secured to the nozzle-body and retaining the sleeve in position, and deiiector-jaws pivoted to the nut or plate, having tailpieces acted upon by the laterally-projecting cam-ribs of the sleeve, and provided at their sides with air-inlet openings for inducing air-currents when the nozzle is in use, substantially as described.

5. The combination of a nozzle-body hav-A ing a screw-threaded end, a cylindrical bear- IIO defieetor jaws in advance of their pivotpoints, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
